- Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed September 2, 1916. Serial No. 118,194.

To all whom it'may concern: I

Be it known that I, Trrnononnv HENRY Know, a citizen of the United States,residing at Breckenridge, in the county of Summit and State of Colorado, have invented certain new and useful Improvements in Ovens, of which the following is a specification; I r

This invention relates to an improvement in ovens of stoves or ranges.

The object of this invention is to provide means for oausing'the bottomand trays to be moved outwardly upon the opening ofthe door, whereby access may be had to the article being cooked for the purpose of examination or the removal from the oven without the danger of injury from burns A further objectis toprovide means for disengaging the actuating means of the trays from the oven, whereby the ovendoormay be readily opened without disturbing the trays when it is desirable.

The invention relates to still other novel features of construction and the combinations of parts which will be hereinafter more fully described and pointed out in the-claims.

In the accompanying drawings:

"Figure 1, is a view in front elevation showing the door closed;

Fig. 2, is a similar view of the door open;

Fig. 3, is a longitudinal vertical section showing the oven door in open position and the movable bottom in an extended position;

Fig. 4, is a similar view showing the movable bottom within the oven and the oven door closed;

Fig. 5, is an enlarged detailed view of the latch mechanism and associated parts.

A represents the oven, which may be of any approved shape, but which as shown in the drawing is practically square.

A movable bottom B is m unted within the oven A, and is adapted to rest and move over the base or bottom 1. A telescoping lever consisting of parts 2 and 3 is pivotally connected to the rear side of he movable bottom B. A bracket 4 is connected to the rear side of the oven A in th uppermost corner, and is provided with an elongated slot 5. Adapted to travel in the elongated slot 5 is a roller 6, which roller is connected to the outer free end of the telescoping memher 3. The inner end of the telescoping members 2 and 3 is provided with rollers 7 and .8, each of which is adapted to engage thelcompaniontelescoping member, in order to reduce asmuch as possible the friction caused by the movement of the movable bottomB.

ing member 2 for causing the movable bot tom to be moved either in the forward or rearward direction.

This crank shaft --is substantially U- shaped, the lower portion 10 of which is adapted to extend horizontally along the bottom of the oven toward the outer right hand side, the outer end of which is then bent up. thereby forming another crank shaft 11. A draw bar 12, is pivotally connectedtotheouter end of this crankshaft 11, and is adapted to extend horizontally along the outer wall of the oven toward the front thereof. the outer endbeing suitably supported upon a pin or roller 13, the said draw barhaving atits outer end a suitable recess 14.

A bracket 15 is connected to the oven door 1 C. This bracket is provided with a vertically arranged latch 16. which is received in a dove-tailed slot 17 of said bracket. The upper end of this latch is provided with a knob 18 adapted to register with the recess 14, when the latch is held in its uppermost position by a cam 19 wh ch is pivotally connected at 20 to the bracket 15.

It will thus be seen that upon the movement of the door the draw bar will be actuated, thereby causing the crank shaft to oscillate, the oscillation of the crank shaft causing the telescoping member 2 to be moved and imparting a movement to the movable bottom B, whereby it will be moved either in a forward or rearward direc on, as disclosed in Fig. 4.

When the bottom is in the rearward position the said telescoping members 2 and 3 are adapted to telescope and assume a comparatively vertical position at the rear of the oven. The cam 19 is provided with a handle 21, which when in its lowermost position diseha'ages the latch 16 from the draw bar 12. This arrangement permits of the movable bottom B being pushed manually so A crank shaft 9 is mounted ,upontlie back Copies 015 this patent may be obtained-for When the latch 16 is in its lowermost position, it does not register with the recess 14: of the draw bar, thereby permitting the operator in this instance to open and close the oven door for inspection of the articles being baked without disturbing same, which is often desirable when baking...

It will thus be seen that with this con-- struction, I have provided a means which 'can be arranged according to the desires of the operator; that is, the mechanism can be arranged in such a manner that the movable bottom B will be forced outwardly from the oven, when the oven door is open, if it is desirable. p

On the other hand, the mechanism can be so arranged that the .oven door can be readily opened and closed without interferingwith or disturbing the movable bottom after it has been moved back into the oven.

I claim: 1

1. The combination with an oven and a door, of a movable bottom, telescopic members connected with the movable bottom and rear of the oven, a crank shaft connected. to one of the telescopic members, a draw bar pivotally connected to the crank shaft at one end and having its outer free end connected to the oven door, whereby upon the opening and closing of the door, the movable bottom will be moved from and into the oven,

'2. The combination with an oven and a door, of a movable bottom, telescopic members connected with the movable bottom and rear of the oven, a crank shaft connected to one of the telescopic members, a

the movable bottom will be moved from and into theoven 3. The combination with an oven and a door, of a movable bottom,tel'escopic members connected with the movable bottom and rear of the oven, a crank shaft connected to one of the telescopic members, a draw bar pivotally connected to the, crank shaft at one endand having its outer free nd slidablysupported upona pin, a vertically adjustable latch carried by the door, which, when in its upper or lower position is adapted to engage or disengage the outer free end of the draw bar.

4;. The combination of an oven and door, a removable bottom, a slotted bracket, an extensible lever pivotally connected at one end to the movable bottom and slidably connected at the, other end with the slotted bracket, a crank shaft pivotally connected with the extensible lever, a slidably pivoted draw barpivotally connected. with one end of the crank shaft, a bracket connected with the oven door in position to engage a notch in-the draw bar to slide the latter and actuate all its connected parts when the oven door is moved.

In testimony whereof I aflix my signature.
